<em>Simplify, expression, order of operation, PEMDAS
</em>
For this case we must simplify the given expression, we must take into account the order of operation (sequence in which operations must be performed) known as PEMDAS:
P: Parentesis
E: Exponents
M: Multiplication
D: Division:
A: Addition
S: Subtraction
In the given expression, we see that we have multiplication and addition, according to the PEMDAS rule, we must first do the multiplication:
So:
We multiply, taking into account that:
We add similar terms:
Different signs are subtracted and the sign of the major is placed:
Answer:
By simplifying we get 13 as a result.
